General description In general, the combined back rest and carrying bag embodying the invention comprises a back member and a thigh support member hingedly affixed at longitudinally spaced locations to an intermediate seat portion which may be a fabric web. An adjustable back brace is hinged to the back member for supporting same at a variable inclination on a supporting surface such as the ground. The ends of a rope are adjustably fixed by jambing grommets to the upper side edges of the thigh support member, the rope extending through openings in the upper side edges of the back member and around the back thereof for determining the angle between the back and thigh support member. Thus, the back and thighs of a person seated on the web are supported in a comfortable inclined position by the back and thigh support members, respectively. The side edges of a rectangular bag sheet are affixed to the side edges of the back member, the midportion of the bag sheet being movable away from the back member to define a chamber therewith, and with said web, for carrying articles. The portion of the rope behind the back member may be used as a carrying handle for carrying the device as a carrying bag.

Detailed description The device 10 (FIGURES 1 and embodying the invention basically comprises a substantially rectangular back member or panel 12 and a longitudinal aligned thigh support member or panel 13 of preferably similar width afiixed to and separated by a seat element a panel 14. The members 12 and 13 are pivotable with respect to each other along their opposed edges and with respect to the seat element H. In the preferred embodiment of the invention shown in FIGURES 1 and 5, the seat ele ment 14 comprises the intermediate portion of an elongated flexible web 11 which extends substantially throughout the longitudinal extent of the members 12 and 13. The web 11 is preferably of medium weight canvas but other materials including flexible plastic sheeting or other fabrics may be used if desired.

The upper edge 16 (FIGURE 1) of the back member 12 is preferably convexly curved as are the concave lower edge 17 and convex upper edge 18 of the thigh support member 13. The nesting curves of the edges 17 and 18 allow members to be sequentially cut from a piece of material with minimum waste while providing a pleasing appearance. If desired, the edges 16, 17 and 18 may be straight. The back and thigh support members 12 and 13 are preferably constructed of a substantially rigid and relatively light weight material capable of limited resilient flexure. Although the present embodiment uses 4; inch thick plywood, other materials such as cardboard or plastic panels or the like might be used if desired. The web 11 includes side flaps 19 which fold over the side edges of the members 12 and 13 and a similar end flap 21 which folds over the upper end of the back member 12. The web 11 including the flaps 19 and 21, is in the embodiment of FIGURE 1, attached to the back and thigh support members 12 and 13 by a suitable adhesive of any convenient type although other fastenings including stitching, staples, rivets or the like may be used if desire-d.

A pad 22 (FIGURE 2) may be disposed upon the seat portion 14- and may be afiixed thereto by any convenient means such as adhesives. In the particular embodiment shown, the pad 22 comprises a slab of relatively dense resilient material such as foam rubber.

The side edges of a flexible rectangular bag sheet 27 are afiixed to the back member 12 adjacent the sideward edges thereof and are preferably covered by the flaps 19.

The bag sheet 27 is preferably of the same material as k the web 11. The bag sheet 27 is wider than the back member 12 approximately by twice the longitudinal extent of the seat portion 14. The bag sheet 27 extends from the bottom edge of the back member 12 upwardly almost to the upper edge 16 thereof. The upper and lower edges 28 and 29 of the bag sheet 27 are freely movable so that the bag sheet 27 may be folded flat against the back member 12 as shown in FIGURE 1 or may be freely pulled forwardly away from the back member 12 (FIGURES 3, 5 and 7) to define therewith and with the seat portion 14 a chamber 3-1 of large maximum volume (1800 cubic inches in the embodiment shown) for receiving articles to be carried. The forward portion of the bag sheet 27 is normally reinforced, when the device 10 is used for carrying, by the thigh support member 13 as indicated in FIGURE 5 and hereinafter discussed, the members 12 and 13 acting to shield and protect articles placed in the chamber 31.

A pair of circular grommets 32 reinforce openings through the back member 12 near the upper corners thereof. A pair of jamb grommets 33 define a substantially key hole shaped opening through each of the upper corners of the thigh support member 13. The narrowed ends of the jamb grommets 33 are preferably opposed as in FIG- URE 6.

The midportion 37 (FIGURE 2) of an elongated flexible element, here a rope 36 normally lies, when the device 10 is arranged as a back rest as shown in FIGURE 1, behind the back member 12 between the grommets 32. The legs 34 of the rope 36 extend from the midportion 37 forwardly through the grommets 3-2 and through the enlarged portion of the corresponding jamb grommets 33. The transverse portions 35 of the rope 36 emerging from the jamb grommets 33 then cross the width of the forward or under face of the thigh support member 13 to pass upwardly or rearwardly through the narrow portion of the jamb grommets 33 on the opposite side. The ends 39 of the rope 36 are preferably terminated in knots 38 or by other enlargement means such as suitable clips, not shown, or the like to prevent inadvertent removal thereof from the jamb grommets 33 should said ends slip from the narrow portion of said jamb grommets into the wide portion thereof. It will be noted that tensioning of the rope 36 due, for example, to the weight of a person seated in the device 10 in its orientation of FIGURE 1, will cause the legs 34 of the rope 36 in the large part of the jamb grommets 33 to move toward the narrow portions thereof, thereby tightly Wedging or jambing the rope ends 39 into said narrow portions to fix the ends 39 with respect to the thigh support member 13 independently of the knots 38. The jambed ends 39 are released by outward movement thereof toward the wide part of the jamb grommets 33. Thus, the effective length of rope 36 between the jamb grommets 33 may be adjusted and looked between such adjustments to furnish the angle or distance between the members 12 and 13 desired.

upper end of a vertically elongated and preferably upwardly eorivergently tapered back brace 41 is hinged on' mthetbackfac'e of "the ba'ck niernber 12 adjacent its upper end and extends snbstaritially'to'the bottom edge of theba'kbf theknein-ber 12" to form a cloth hin e 46. In

icelitimay also be us edaas a baek rest without:

the members 12 and 13 to bring said members into the substantially spaced, upstanding condition of FIGURE 5. The midportion of the bag sheet 27 may now be pulled forwardly away from the member 12 and toward its position of FIGURE so that articles to be carried may be placed within the chamber 31. Thereafter, the cover sheet 61 may be placed over the chamber31 and fastened by means of the hook 62 into one of the holes 47 in the back brace 41. The upwardly pulled midportion 37 of the rope 36, with the knots 38 abutting the grommets 33 will be long enough to be used as a shoulder strap or to be placed *behind the neck and in front of the shoulders of the user for carrying the device 10 as a knap sack. The midportion 37 may be shortened for use as a hand grip or handle by unlocking the rope ends 39 from the jamb grommets 33, axially adjusting said ends with respect to said grommets 33 and finally relocking said ends in said jamb grommets. Alternatively, the rope ends 39 may be left undisturbed in the jamb grommets 33 and the two portions of rope 36 passing forward of the support member 13 may be seized at their midpoints and drawn up until they lie next to the midportion 37 whereby all three may be grasped or hung on a hook. The members 12 and 13 tend to move toward each other and curve around and snugly surround the load in the chamber 31 when the rope 36 is tensioned by an upward pull on the rope midportion 37. For thinner loads or when the chamber 31 is empty, the member 13 is moved upwardly as a whole with respect to, as well as, toward the member 12 upward urging of the rope midportion 37 acting to make the device thinner. In such flat condition, the device 10 may be readily stored in a small space. The chamber 31 may, if desired, be loaded substantially as above described but with the back member 12 braced nearly vertically by the back brace 41 whereby the device 10 stands up without manual support during loading or unloading.

The grommets 33 and 32 are positioned so that an upward pull on the rope midportion 37 tends to move the upper end of the member 13 toward the upper end of the member 12. Thus, if only the bottom portion of the chamber 31 is filled, the upper edge of the member 13 moves inwardly while its lower edge stays spaced from the member 12 so that the member 13 at least partially covers the load in the chamber 31 thus allowing the cover sheet 61 to be omitted -or left open.

If desired, a liner, not shown, may be provided for continuously covering the upper faces (FIGURE 1) of the member 12, the pad 22 and the member 13. In such case the back sheet 67 of the pocket 66 may be omitted and the front sheet thereof is attached along its bottom and side edges to the face of the liner. It is also contemplated that the web 11 and such liner may together comprise a fabric tube, into an open end of which the member 12, pad 22 and member 13- may he slid, whereafter closure of the tube ends, as by sewing, and thereafter addition of the grommets 32 and 33 fixes the members 12 and 13 within the tube, the pad 22, if included, being fixed in said tube by any convenient means, such as adhesives.

Although the above discussion has been primarily di rected toward a preferred embodiment of the device 10, constructed for long life and for a pleasing appearance, at least the broader aspects of the invention might be carried out by a device such as seen in FIGURE 11, of less expensive materials and simplified construction for use as a throwaway to be discarded after a single or limited use. Turning to FIGURE 2, such a throwaway device might be constructed for example by making the back member 12, the seat element 14 and the support member 13 from a piece of cardboard creased and folded at the lines of separation between the parts 12, 13 and 14. An inexpensive grade of heavy twine might be used for the elongated element 36. The pad 22, cover 61 and, for stadium use, the back brace 41 with its cord 8 53 might be eliminated. Even the bag sheet 27 might be eliminated although this would seriously degrade the ability of the device 10 to act as a carrying device except perhaps for single relatively large boxes or thin objects such as papers taken a few at a time.

Although a particular preferred embodiment of the invention has been disclosed. above for illustrative purposes, it will be noted that variations or modifications thereof which come within the scope of the appended claims are fully contemplated.
